richyrich7 and poutrygeists advice is good L110BS, my mate had his gas fire taken out of his 19thC terrace this summer and started using the unchecked chimney with an open fire... a fair bit of the smoke came back into the room, that unpleasent I stopped visiting him - its still carbon monoxide and other nasties, you just see it unlike gas fumes.
As you are in Nottm the Clean Air Act will more than likely apply. Its the Act that rightly stopped the "pea soupers" - not that they bother out where my dad lives (ex-mining village), its like dickensian london when there is no wind! The local City or borough council (ie Gedling, Broxtowe, Rushcliffe etc) should list which localities/areas are Act exempt ie burn any fuel on any appliance - but these are probably more rural. You can easily buy logburners that are tested and thier emissions comply with the Act -they'll usually have whats called a "secondary air burner" or "airwash" but they cost more than them £100 cast iron things from Machine Mart. The stovesonlive webthing will tell ya which appliances are and aren't exempt.
Don't let all this put you off, its all doable but just more costly so payback time on the works/stove is longer. I'll go this route one day, just can't afford the upfront costs currently.
